How to fix shadow flickering on Manli RTX 5070 OC 12GB GDDR7?
While exploring the sandstorms in Yellow Wind Ridge, I noticed the shadows on distant rocks were jumping around like crazy, which totally killed the immersion. Even though the GDDR7 memory on this Manli card has insane bandwidth, the default voltage curve was hitting a 12-18ms scheduling lag during sudden load spikes. At first, I tried locking the core clock in the NVIDIA Control Panel, but that was a disaster—core temps spiked to 82-86℃ and the fans sounded like a jet engine taking off in my room. I pivoted to VRAM tuning, setting a +200MHz offset and bumping the voltage offset to +0.025V. Using a frame time analyzer, I saw the erratic 14-22ms spikes flatten out to a steady 8-11ms, and the shadow tearing completely vanished. Lowering the resolution to 2K barely did anything; the real breakthrough happened after I recompiled the entire 4.2GB shader cache. Now, VRAM temps sit comfortably at 64-69℃ with power peaks between 215-228W. Checking the render pipeline via HWiNFO, my frame generation time is rock steady at 8-11ms.
